Dr. Pomp studies the genetic architecture of complex traits, with an emphasis on body weight regulation and obesity. Using polygenic mouse models and high throughput approaches integrating genomics and physiology, he identifies genes that control predisposition to a variety of complex traits including energy intake and energy expenditure (e.g. voluntary exercise). In addition, Dr. Pomp studies how these genes interact with each other, with changing environments such as nutritional interventions, and with other diseases such as cancer.
